Humans have been utilizing the land since the beginning of time, building settlements where there was access to water and fertile soils. Over time developments have been made in order to properly manage land use. Agriculture has been the driving force behind land use, but today there are more needs than just agriculture. Needs such as municipal, transportation, energy, recreation, and waste management. . How Soil Solarization Works. Soil Solarization. Agricultural “Warfare”. Current Practice: Herbicides.
